Hello everyone! I recently had the GTT test, and these were my results:

Fasting 94
1/2 Hour 145
1 hr 175
2 hr 147
3 hr 107
4 hr 66
5 hr 76

My symptoms are frequent urination, side/abdominal pain, mood swings/shaky if I wait too long to eat, feeling nauceous and like I might pass out after meals, dizziness, often feeling like I might pass out, tingling from my shoulder down to my fingertips, and tingling from my hip down to my toes - also cold hands and feet while this is happening. One doctor seemed to think I might possibly have glucose intolerance or pre-diabetes. Another thought I might have hypoglyemia. I was diagnosed with hypoglycemia in 2006 based on symtoms alone - but I'm seeing an endocrinologist this month at UVA for further help. Thanks in advance!

Glucose intolerance
Glucose intolerance has no symptoms. It is usually discovered when blood glucose levels are normal or little above the normal. Diagnostic criteria for glucose intolerance are:
1. blood glucose level less than 7.0 mmol/L (<128 mg/dL) when hungry (fasting), and
2. glucose level between 7.8 and 11.0 mmol/L (142-200 mg/dL) 2 hours after glucose tolerance test (ingesting 75g glucose).
Your glucose level when fasting (hungry) was 95 and 2 hours after the test was 147 which means that the first test was positive. In such cases another test should be done but this time by ingesting 100g glucose and measuring the glucose level 1, 2 and 3 hours after the glucose ingestion.
Did you repeat the test with 100mg glucose or you made only one test?

No, that was the only test I've done - except for the one I had done in 2005 which was a 3 hour test. However, I went to UVA on Monday and they would like me to fast from 8pm Thursday evening-12pm Friday afternoon and would like to take my blood again at 12pm. I'm not sure what this will show. They also disagreed with the other endocrinologist and stated that I may not have prediabetes since my levels were only slightly higher than normal. He said this could be due to stress. Do you know if this is true?? Thanks for your response!

One other question - is it possible to have diabetic neuropathy with pre diabetes? Or does it have to be a more advanced stage of diabetes? Thanks.

Another glucose tolerance test but this time with 100 g glucose and measuring the glucose level after 1st, 2nd and 3rd hour will clear the situation. There are other referent values for this test.
Stress can cause disturbances in the blood glucose regulation. Stress is also involved in the pathogenesis of the diabetes type-2.
Unfortunately glucose intolerance can have the same long-term consequences (neuropathy, nefropathy, retinopathgy and atherosclerosis) like the real diabetes.
